What evidence is there that the plates have moved?

Some evidence there is about the plates is that if you put our continents all together, they look like they'd fit together, like a giant puzzle. Another thing is that on some edges of the continents, the same fossils were found, suggesting that the continents were once joined together. These plates are called tectonic plates, and move slowly, and then sink down in most cases. Convection Currents are vertical movements of fluids driven by heat. There are three different types of boundaries: Convergent, Divergent, and Transform. The two plates are Oceanic and Continental.

Wind

Wind changes Earth's surface in many ways. Wind can sometimes even cause natural disasters like Tornadoes, or Hurricanes which in their turn, shape and change the Earth's surface even more.

Water

Water also changes the Earth's surface. Water can erode the surface layer of Earth, leaving deep crevices in it. An extreme case of this is The Grand Canon.

Ice

Lastly, but definitely not least, is Ice. Ice changes the Earth most drastically out of all of the pictures I have shown. Ice causes drastically effects like decaying plants, killing plants, even killing people, and animals in some cases! Ice cover the whole surface and thaw, causing a flood most severe.

Eroding its way out of your heart!

Erosion

Erosion is the process of being eroded, or steadily destroyed, by wind, water, or other natural events or things. The types of erosion are Water, Wind, Glacier, Soil, and Sea erosion. The erosion that causes the most damage is Glacier. A combination of water, ice, and picked up sediment creates a powerful erosion machine. The least damage created erosion is Soil. Soil erosion takes the top layer of soil and makes it infertile. It creates less food and plants for us, but nothing is destroyed.

Fossils are us. (Or they used to be)

Law of Superposition

The Law of Superposition is the law stating that if there are layers in an object, the youngest or most recently placed thing would be at the top, while the oldest or longest placed thing is on the bottom.

'How can fossils tell us about the history of the Earth?'

Fossils can tell us many things about Earth's history. If you look at the picture, you can infer that that animal once existed in, or on Earth.

'Are all fossils the same?'

No. Fossils can be all different shapes and sizes, depending on the animal, plant, or other object that they formed from.

Rocky Road (And Minerals!)

Igneous Rock

Igneous Rocks are rocks that form directly from the cooling of magma.

Sedimentary Rock

Sedimentary Rocks are rocks that form as a result of layers settling, and compressing into rock.

Metamorphic Rock

Metamorphic Rocks are rocks that arise from the transformation of existing rocks.

The Rock Cycle

The Rock Cycle is a cycle that rock go through. It can change Igneous Rock to Metamorphic Rock, and vice versa. For example, Igneous Rock changes to Sedimentary Rock through Weathering, Erosion, Burial, and Compaction.

Minerals.

Minerals form from decaying organisms and as a result of changes in the Earth's crust. We can identify minerals by their colors, shapes, sizes, streak, luster, or hardness.

Things I have enjoyed

I have enjoyed many things about the activities in this unit. The best thing was probably doing this flyer, seeing as it was very fun. The stations were also pretty rad. :3
